As by mentioning in the following description, inject the component housing that frame 250 can comprise the outside forming mobile terminal 100 or the ad-hoc location being configured to by supporting window 210 in mobile terminal 100 being installed window 210.Fig. 3 and Fig. 4 shows injection frame 250 and comprises housing 101 or 102 (more particularly, comprising procapsid 101).
Being made up of optical transmission material due to window 210 and being arranged on the top of display unit 151, therefore user can check the content of display on display unit 151 by window 210.
In addition, as shown in Figure 3 and Figure 4, at least one metal frame 230 can be attached to the edge at the back side of window 210, thus prevent the flexural deformation of window 210 and strengthen and the coupling mechanism force injecting frame.After a while by the shape of detailed description metal frame 230 and attachment methodology etc.
Meanwhile, as shown in Figure 3 and Figure 4, display unit 151 can be arranged on the below of window 210.Display unit 151 arranges according to the mode of the rear-face contact with window 210, or can be arranged on below window 210 according to the mode with the spaced apart preset distance of window 210.When the mode come in contact according to the back side with window 210 arranges display unit 151, preferably display unit 151 is formed as being less than window 210 more or less, to avoid metal frame 230 interfere with the edge at the back side being attached to window 210.
As described in explanation above, display unit is not limited to the assembly discrete with window 210.Such as, display unit 151 can become one with window 210 substantially.In the case, the window 210 that the execution mode of middle explanation is described below can be considered as display unit 151.
The side (that is, upper and lower, limit, left and right) and the metal frame 230 that inject frame 250 and window 210 combine the outside forming mobile terminal 100, or injection frame 250 will be installed in mobile terminal 100 inside.Fig. 3 with Fig. 4 shows the housing injecting frame 250 and comprise the outside forming mobile terminal 100 together with window 210.Thus, if inject the outside that frame 250 defines mobile terminal 100, then injection frame 250 can be called frame portion.
The numerous embodiments according to mobile terminal of the present invention is described in detail referring to Fig. 5 etc.In order to described below clear for the purpose of, in Figure 5 display unit 151 is not shown.
Fig. 5 is the sectional view along line of cut III-III of the mobile terminal shown in Fig. 3.
With reference to Fig. 5, mobile terminal 100 according to the present embodiment comprises the window 210 be made up of optical transmission material, at least one metal frame 230 of the dorsal edge being attached to window and the injection frame 250 that combines with side and the metal frame 230 of window 210.
In the case, the optical transmission material of any type can be comprised for the type of the material of window 210.Generally, optical transmission material comprises glass.Alternatively, optical transmission material can comprise the transparent material of the random synthesis as synthetic sapphire.Preferably, window 210 can be made up of tempered glass materials.
In the case, toughened glass is the glass of tempering in such a way: heated by plate glass at close to the temperature of softening temperature, is cooled rapidly by the glass heated with the outside being changed glass by compression stress and by the inside of tension change glass.The impact resistance of the toughened glass manufactured in such a manner and thermal endurance are all better than impact resistance and the thermal endurance of simple glass.Further, bending strength is 3 to 5 times of simple glass.
Thus, if window 210 is made up of toughened glass, then the distortion caused by moment of flexure can become the distortion being less than simple glass and being caused by moment of flexure.But, the surface of toughened glass defines compression with supports outer weight, and defines tensile stress in toughened glass inside.Therefore, if be applied with the external force of the bending strength being greater than toughened glass to toughened glass, then toughened glass may jeopardously be pulverized.This is similar to the situation of simple glass.Specifically, if apply the external force larger than the bending strength of simple glass to simple glass, then simple glass may split.In addition, the glass split also may break for some pieces.
Therefore, when the material using toughened glass as window 210, in order to strengthen fail safe and durability, sizable bending strength is needed.In the case, ensure that the rigidity of window 210 according to mobile terminal according to the present invention 100 by least one or more metal frame 230 being attached to the dorsal edge of window 210.Fig. 5 shows, by adhesive A, metal frame 230 is attached to window 210.
In addition, the metal frame 230 being attached to the back side of window 210 can also strengthened playing a role in the coupling mechanism force between injection frame 250 and window 210.To be specifically described this in the disclosure after a while.
Meanwhile, the injection frame 250 shown in Fig. 5 is the housings of the outside that together form mobile terminal 100 with window 210.Specifically, inject frame 250 to be formed by inserting injection molding (insertinjectionmolding).
More particularly, inject frame 250 to be formed by inserting injection molding in the following manner: by attaching, the window 210 of metal frame 230 inserts mould, then makes the side of window 210 (that is, edge) and metal frame 230 can be wrapped by mould.Inject frame 250 to be formed by injection molding, the material be injected in mould can comprise the plastics of such as Merlon and ABS etc. or the pottery of such as aluminium oxide and zirconia etc.
Thus, owing to be inserted into around the side of the window 210 of mould and metal frame 230 and the mode then making injection material solidify is formed inject frame 250 by inserting injection molding according to being injected by the injection material of fusing, therefore between injection frame 250 and window 210, do not produce gap.
Specifically, due to be by insert injection molding with the mode that the side of window 210 is wrapped up define inject frame 250, inject frame 250 if therefore observed from the outside, inject frame 250 seem seemingly window 210 with inject frame 250 at grade continuously and couple together smoothly.
Due at window 210 and inject between frame 250 and do not produce gap, therefore can't see the adhesive A together with being attached to metal frame by window 210 outside.Therefore, it is possible to strengthen the exterior appearance of mobile terminal 100.
In addition, when the insertion injection molded process injecting frame 250 by be in liquid injection material cool and solidify time, inject frame 250 and encase window 210 and metal frame 230 securely to strengthen the coupling mechanism force between injection frame 250 and window 210.
Meanwhile, with reference to Fig. 5, metal frame 230 preferably includes accommodation section 231, and this accommodation section is used for holding the injection material for the formation of the part injecting frame 250 wherein.
Fig. 5 shows metal frame 230 and bends twice in its width direction to have shape.Specifically, metal frame 230 is built as and has top plate portion, vertical portion and bottom parts.Further, accommodation section 231 is formed between top plate portion and bottom parts.Injecting the insertion injection molded process of frame 250, be accommodated in after in the accomodating unit 231 constructed as described above at the injection member of fusing, outside in accommodation section 231 has been played effect in encasing all securely enabling the injection member being in liquid state (changing into solid-state state from liquid) by accommodation section 231.Namely, if be accommodated in the injection member of the liquid state in the accommodation section 231 of metal frame 230 and solidify in the top plate portion of metal frame 230 and the injection member of bottom parts ambient dynamic simultaneously, then while the strength of the top plate portion and bottom parts that encase metal frame 230 works, define solid-state injection material.
Therefore, metal frame 230 provides bending strength by being attached to the back side of window 210.If metal frame 230 is configured to have the accommodation section 231 partly holding injection material, then inject frame 250 more to lock mutually securely with metal frame 230, while window 210 wraps by injection frame 250, the window 210 significantly enhancing attaching metal frame 230 and the coupling mechanism force injected between frame 250.

In the following description, the attaching of being carried out between window 210 and metal frame 230 by adhesive A is understood in detail.
Figure 14 is the partial section of the mobile terminal according to another execution mode of the present invention.In order to described below clear for the purpose of, in fig. 14 injection frame is not shown.
With reference to Figure 14, metal frame 230 according to the present embodiment utilizes adhesive A to be attached to the edge at window 210 back side.
In the case, adhesive A refers to so a kind of material, and this material is being coated in bonding region by liquid state and can not be stripped after solidifying, and can not being destroyed from figure system of this material.Bonding agent is formed by polymer usually.Specifically, bonding agent uses liquid polymer.Alternatively, bonding agent use due to liquid phase low molecule combine after polymerization and the polymer that produces.Alternatively, use bonding agent with attaching Cucumber in the mode melting solid polymer.
Meanwhile, with reference to (a) of Figure 14, the surface of metal frame 230 being attached to window 210 can form the groove 237 of desired depth.
(a) of Figure 14 shows groove 237 and is formed on the end face of the metal frame 230 being attached to window 210.Thus, be coated with on the surface of adhesive A if groove 237 is formed in, then adhesive A flows and flows in groove 237 further on the attach surface of metal frame 230, owing to being all coated with adhesive A on all inner surfaces of groove 237, therefore increases the surface covered of adhesive A.Therefore, the coupling mechanism force between window 210 and metal frame 230 is further increased.
With reference to (b) of Figure 14, perforation 239 can be set to a surface of the metal frame 230 being attached to window 210.
If form perforation 239 on the coated surface of adhesive A, then adhesive A penetrates perforation 239 and coated, as shown in (b) of Figure 14, and is applied on the preset range of surrounding of perforation 239.Thus, if be provided with perforation 239 to metal frame 230, then increase the area of adhesive-applying A to strengthen the coupling mechanism force between window 210 and metal frame 230.
Figure 15 is the stereogram of the metal frame comprised according to the mobile terminal of another execution mode of the present invention, which includes the partial perspective view of the mobile terminal containing metal frame.
Specifically, (a) of Figure 15 is the stereogram of the metal frame 230 according to another execution mode, the metal frame shown in (a) that (b) of Figure 15 shows Figure 15 is attached to the state of window 210, and (c) of Figure 15 is along the sectional view of the line of cut XV-XV shown in Figure 15 (a).
With reference to (a) of Figure 15, at least one or more a perforation 238 and 239 be set to the one side of metal frame according to the present embodiment.In the case, because the cross section of metal frame 230 roughly defines rectangle, therefore manufacturing process is beneficial to.
With reference to (b) of Figure 15, perforation 238 can be set to the one side being attached to injection frame 250 of metal frame 230.According to the present embodiment, because metal frame 230 has the cross section of rectangle, therefore perforation 238 extends to the one side being attached to window 210 of metal frame 230.Specifically, perforation 239 that metal frame 230 is arranged, the one side that is attached to window 210 with metal frame 230 is arranged, the perforation 238 that is attached to the one side injecting frame 250 is identical.Certainly, be similar to if metal frame 230 is formed to have shape (as Suo Shi Figure 14 (b)), perforation 239 that metal frame 230 is arranged, the one side that is attached to window 210 can from metal frame 230 is arranged, the perforation 238 that is attached to the one side injecting frame 250 is different.
Mobile terminal shown in (b) of Figure 15 be according to utilize adhesive A by window 210 and metal frame 230 mutually attaching get up and then utilize bonding agent B by metal frame 230 and inject the mode that the mutual attaching of frame 250 gets up and manufacture.The effect increasing the area being coated with bonding agent B by forming perforation 238 repeats with the formerly description with reference to Figure 14, therefore omits its explanation.
Thus, perforation 238 is set by the one side injecting frame 250 that is attached to metal frame 230 and utilizes bonding agent B by injection frame 250 and metal frame 230 attaching mutually, very strong coupling mechanism force can be provided.
Meanwhile, as the formerly description of (a) with reference to Figure 14, the one side to the injection frame 250 of the attaching of metal frame 230 is provided with the groove (not shown in FIG.) of desired depth to strengthen coupling mechanism force.
In the following description, various schemes metal frame 230 being attached to window 210 are described with reference to Figure 16 and Figure 17.
Figure 16 is according to the window of the mobile terminal of one embodiment of the present invention and the upward view of metal frame being attached to this window.In order to described below clear for the purpose of, from figure, omit the assembly except window 210 and metal frame 230.

When window 210 is made up of tempered glass materials, create the stress on toughened glass surface and the stress in toughened glass to keep balance therebetween.If be applied with the external force of the bending strength exceeding toughened glass as mentioned in description before to window 210, then window 210 is likely ground into fragment.Therefore, when the material using toughened glass as window 210, need to ensure that larger bending strength is to strengthen fail safe and durability.
According to the present embodiment, in order to ensure the rigidity to the moment of flexure acted on window 210, metal frame 230 is attached to the edge at window 210 back side.Each metal may be used to the material of metal frame 230 to provide predetermined strength.Preferably, metal frame 230 is made up of stainless steel material.
With reference to (a) of Figure 16, pair of metal frame 230a and 230b corresponding with the vertical length of window 210 can be attached to left hand edge and the right hand edge at window 210 back side respectively.
Due to vertical length its horizontal length about generally of the mobile terminal 100 shown in Fig. 2, if apply the moment of flexure of formed objects, then the bending displacement on vertical direction may be greater than the bending displacement in horizontal direction.In the case, if pair of metal frame 230a and 230b of the vertical length corresponding to window 210 to be attached to respectively left hand edge and the right hand edge of window 210 as shown in (a) of Figure 16, then the bending strength on vertical direction can be increased.
In addition, can by the mode attaching metal frame making metal frame be spaced apart from each other on the length direction of window with predetermined gap.
Specifically, according to the execution mode shown in Figure 16 (b), they are attached to left hand edge and the right hand edge of window 210 by the mode be spaced apart from each other with predetermined gap along the length direction of window 210 by making 4 metal frames 230a, 203b, 230c and 230d.
